Hello,
I've got 486 PC which I'd like to use with a bunch of ex-industrial ISA cards to run some of my experiments. However I ran into some address/IRQ problems, which most likely are caused by network card, which is PnP autoconfiguration-something. (Card in question is Allied Telesis AT-1700BT). So, I wanted to change its settings for set of known-free memory locations and IRQ. And that's where the problem is. According to the user's manual, special software is needed to change the settings, which was supplied on floppy. I searched google, archive.org and some other funky websites, but no luck. I even contacted Telesis directly, but they said that it's way too old, and they can't help me with that. So finally I decided to ask here if anybody could help me with getting that software.
I could just buy different network card, but I can't afford that now and in the near future. This one came with the PC, so I want to just use it.
I could in theory change settings on the other cards, but some of them have fixed address logic and/or fixed IRQ connections (I don't want to physically modify them) and after whole day of thinking how to fit all that in AT address space.... there's only one option, so the network card must cooperate.
Plan B is to desolder configuration EEPROM, find suitable adapter for my programmer and rewrite its contents, but I'd have to figure out how it's organized, as datasheet for the main chip (MB86965A) doesn't specify it clearly.
Manual for card in question is available at archive.org: https://archive.org/details/generalmanual_000016073
